Warming commitments
There’s been quite a lot of recent discussion about warming commitments. It started with an article by Bob Berwyn called Net Zero Emissions Would Stabilize Climate Quickly Says UK Scientist, followed soon after by one saying [w]arming already baked in … Continue reading
Have CO2 emissions peaked?
I noticed, as has Stoat, that Ken Caldeira and Ted Nordhaus have a bet about whether or not we’ve reached peak CO2 emissions. Specifically, the bet is Between 2021 and the end of 2030, annual fossil fuel emissions (excluding carbonation) … Continue reading

The impact of 4C of global warming
On a number of occasions I’ve highlighted Kevin Anderson saying At 4oC most of the scientists I talk to about this, and the social scientists as well, would say it’s incompatible with organised global community. I don’t know if this … Continue reading

Greater future global warming?
Before I go out I wanted to briefly mention a recent paper by Patrick Brown and Ken Caldeira called [g]reater future global warming inferred from Earth’s recent energy budget. Patrick Brown already has a nice blog post about this with … Continue reading
Hawking is wrong
I guess the big alarmist news at the moment is that Stephen Hawking has been quoted as saying: Trump’s action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, … Continue reading

We might not be certain, but…..
Bret Stephens, the newly appointed Op-Ed writer for the New York Times, has released his first column to much criticism. It’s a rather strawman-laden column in which he essentially argues that it’s okay to doubt climate science, and/or climate policy, … Continue reading
Maximum warming
There’s an interesting new paper by Katharine Ricke and Ken Caldeira called Maximum warming occurs about one decade after a carbon dioxide emission. The basic result of the paper is that the median time between the emission of some CO2 … Continue reading
